Be it known that I lVinLiAM E. @Home Y a citizen of the United States,-and residing at Hamilton, in the county' of Essex and State of Massachusetts, have invented cerytain new and useful Improvements in Snapf iol- `Fastenfir-Assembling Machines, or' `which the following is a specification.

This invention relates to machines for attaching members --o separable 'astenings tol their carrying parts, which latter -may' be 'garments such as coats or gloves, or other articles such asV carriage and automobile curbtains. -For the purpose of brevity of de-r scri tion without intendinff it as a limitine 7 L3 #-5 term, the carrying` part will be hereinafter referred to as fabric.

There are now on the `market separable i fasteningsv of such structure as to render it practically essential that the members shall 1besecuredto` the fabricin a predetermined relationship to the line of pull on the fabric which is held by the rseparable fastenings,

` and so that` separation of the two members 'of the` tastenings .cannoqbe effected exceptingivlien one member dccupies apredeter 'j mined position` rotative relatively to the l other member. j

v l And theref are fastenings which, for other reasons, such as their being non-circularin outline, need to be secured 4Ito theirk carrying fabric Withainiforniity.

For instance, the socket members a shown in i the accompanying drawing'swhich illustrate "eine` embodiment of my invention,` are ellip- `tical or elongated in form; eahhavin'g a esita-ble that major and minor l "It In, row of these 1n`embers,such as when ein-- pqloyed in lieu of buttonholesoa garment `tiltcurtain, shall all be securediturned the saine way relatively tothe edge of the garment orcurtain.`

f Qne'oi the objects'ota my invention is tol provide a machine for assembling the snapfastener` members vwith the' carrying yfabric,` ivitl uniformity in the respect above nicntion d, and so" as to render it unnecessary to relyu'pon the careofithe operator to prevent aliixjing a member. turned improperly, or

A, vfurther object is yto provide a. machine ,Il i

of this character haring means for indicating;` when the supply of fastenings in 'the chute or-magazin'e is nearly exhausted, or if a ldefective 'fastening member, or one wrongly carried, is about to=reach position for delireryito the clencliing mechanism.

To these ends'the invention consists in the a shall now proceed to describe and claim.

Similar *reference characters indicate the saine or similar parts in all of the figures. Y The base 30 of themaclune which may be provided with tool or worlnsupporting@ wings 3l (Figs. l and Il), is shown as supported upon suitable legs Depending from the base 30 is a bracket 33 to which a notl lever Slis pivotally connected, as at 35, said latter` being pivotally connected to the bracket 33, and the upper endvof the link 37 being pivotally connected to the top lever 39' which is pivoted at 40 to the arm 41 of the machine. Suitable stop devices .such as a screw 42 will be employed to limit the movement of the lever 39 in' one direction,

under the'influence vof springs, if desired, said springs notg-being'slown. .One end of the leverff 39. has a link connection' 43 with the. uppei.L end of a plunger 44, movable vertically in suitable ways'ca-rried vby the head 45, the lower end of said plunger having a centering stud'46 which is adapted to enter the hole of the socket member a, said stud being provided with a reduced neckl so that when the stud enters the hole of the-member the spring jaws of said member-'a will engage the reduced neck of the stud 46 for a purpose hereinafter described;

Supported by the base of the machine is the'anvil 47, which is elliptical in outline and somewhat concave, to correspond with the shape of the elliptical socket membera which is to be attached to its carrying" fabric, this shape being bes illustrated by comparing Figs. 2 and 7.. he anvil 47 has fa yielding iange 48 surrounding' it, said iange being. mounted upon pins 49 which pass throughvopenings inthe base and have heads to limit the upper movement of said a member fr so as to clench the lvprongs thereof to the fabric I) (Figs. 17,18 and 19), the

anvil having a recess 53 to receive the.

stud 46.-

VVhenthe fabric to whichfthe members a are to be attached is inserted above the anvil',

said fabric may be carried to any desired extent inwardly and under the arm 41 (Fig.

1), a curved plate54 guiding said fabric.

This structure permits the fasteners to be, connected to the edge portion of fabric which, as a whole, is pushed in under the arm 41. The desirability of this is due to the fact'that the socket members a are so shaped and constructed that their spring.

jaiisnz (Fig. 19) 'shall extend in a certain direction relatively to the edge of the fabric.

' The structure just described' permits 'the members c to. be secured to`e"ther edge of a quite wide piece of fabric, with the oval-A shaped vmembers a and jaws a? occupying the same positions relatively to such edge,

no. matter which edge is having the members a attached thereto.

As hereinafter described, the devices a .are automatically supplied by a chute or runway',l one by one, and they are individually transferred to position to be acted upon between the plunger' and the anvil to have theprongs o. clenched to the fabric. 1 To temporarily retain each device a vin position, I provide jaws 55 (Figs 4-and 7).suit ably'shaped4 to engage opposite edges of the .device (L, said jaws 'beingl carried by the lower ends of spring arms 56 secured to the sides of the' head 45. In order that the opl -V erativeness -of these spring jaws may be in- 'terrupted, as for instance, when it is desired to have'a device a thrown .out as soon as transferred 'from the chute by the pusher hereinafter described, I provide a cam 57 having a lever 58,'the cam 57 being thin and beveled and adapted to be'forced in between i' 45 when the handle 5.8 is manipulated, such operation resulting in holding one arm56 outwardly, as indicated` at the left in Fig; 6, thus spreadingthe not grip a device a. l

Referring now to the pusher and its mechanism and c'operating devices, a table jaws so that they will one of the arms 56' and the side-ofliead 59 (Figs. 1, 2, 3, and 7) is connected to a bracket 60 depending from the arm 41, as by bolts 6l. The table 59 is provided with ways 62 for the pusher'- 63, having an upwardly and forwardly curved arm 64 the end vof which is connected by a spring 65 to 'a suitably fixed part of thes frame, so that saidsupportedby a back lrib v67. A lever 68 pivoted at 69 and having a'handle 70 has a latch 7l pivotally connected thereto at '72,

, spring will tend to normally retract the pusher toward and against a -cushion 66, v

said latch having a hook 73 and a cam edge 74. A spring 75 connects said latch with the lever 68 and acts in a direction to hold a pin '76 extending downwardly from the latch against 'the side of one ofthe ways 62.. The pusher 63 has a recessed frontedge as best illustrated in Fig. 5, and is formed with a projecting pointed and beveled toe 77 (see also Fig. .7). Projecting over-the toe-77 is'a holder-plate 7 8'so'as to constitute betweenit and said toe a recess foi' a portion of each socketmember a.

A Icam-shaped tripper 79 is carried by an arm 80'pivoted to thetable, as by ascrew- 81, a spring 82 connecting a pin 83. of said normally hold the lcam tri'pper intl-1e position shown in Figs. 2 and 3. When.`the lever 68 is shifted from the position showin'in F ig. 2 to the position shown in Fig. 3, so as arm 80 with a suitably fixed point so-as to Y.

to trans-fer a device a. that has been deposited in front of the pusher bythe chute presently described, to position beneath the plunger,

the pin 76 acts upon the rear face ofthe cam rib 79 and simply pushes the 4latter aside,

' but on the return movement ofthe pusher, under the influence of spring 65, the pin 76 1 30 `engages the outer face of cam-rib 79 and causesthelatch 71. .to he disengagedfrom the j arm 64 scjthat thespring 65 carries'the '"fo`r"tl1e 'best operation of the machinefto yunder -tl'ieminfluence of spring` 35.

vpusher back during the latter u part of its lrear moveniei'in` withor .regard to `the lever 68; This structure trips` thelatch which connectsthevlever'with the pusher so as to insure the, pusher malzing-a 4full back stroke 4 For reasons' hereinafter' explained, itis necessary `render it lcertain'that the operator cannot operate the machine a second tune without having the. plinger'retreat to its'extreuie limit after each preceding operation: Furthermore, this structure results in reyleasing the pusher so that the sprinf, throws` fitjback with force enough to Yjar the ina` "chineaflittle and `facilitate the gravity feed ofthe` device fr. doiin the chute hereinafter described-- It` will be understood, of course,

that'4 after the pusher has been thrown back its spring, `the operator cannot again ad- Vance` the pusherwithout first carrying the lever 68 back far enough so ythat the cam edge 74 ofthe latch 71 will first ride along i )the side of arm Maand then the hookwill y becaused tolrengage the arm 64e, under the y influence of the;spring 75, as shown in so i Fig.

Thepusher is formed or provided with an edgecain 84 (Figs 2,3, and 5), which cam acts, when the pusher is advanced, upon the lug or` projection 85 of the escap'ement pawl 86 which is pivoted to the table 59 at 87, theend of saidlpawl 86 being curved upwardly-,as bestJshoWn at 88 in Fig. 7 to a position to engageone side ofthe arm'89 4of the chute escapement mechanism hereinafter described, sov thateach forward .movement of the; pusher will cause the' chute escapeuient to be actuated through the medium of said pawl In order that the'escapeinent i .guay `belockedfso that it can act only at the .Y "livery, `last of the stroke oft the pusher rearwardly,` the `pawl `86 is forined with a shoulder-90 adapted.to` beengaged'by a loclrslide 91 having-.anarm 92`connected`by a springr 93` {Fi-g. 2) with a suitably xed point, said slide` '.ha'vingr also a shoulder y94 against which one edge of the lever 68 will Contact .when said leverfis moved rearwardly.- When the lever 681smoved'to'theposition shown 1n Fig. 3, the canil has acted upon the pawlS `to swingthe latter, the shoulder 90 Ofthe pawll'ieing thus moved aside .so as to permit the springr Q3 to aulvance` the lock slide to the position -shown 1n Fig'. 3.

be pushed back until its end escapes from the shoulder 90 of the pawl 86, so'that said pawl, by the pressure against it of the arnoF 89 under the influence of a spring hereinafter described, will return to the position shown in Fig. 2. 1

Each device c, when it leaves the chute hereinafter described, lands upon. the upper surface of a slide 95 beneath the pusher 63 and which projects forwardly therefrom as shown in Fig.. 7, the prongs of the device a bearing upon said slide'.` The slide 95 has a :slot 96 which receives a pin 97 projecting downwardly .from the pusher so as to permit a relative movement 4ol the slide and pusher,

is provided with a hardened steel facing 98, the edges of which arecut away to form rejcesses 99 (Figs. Q and 5), the .portion of the -facing 98 which forms thefront margins of said' recesses being' preferably -slightly beveled, for a purpose presently explained. A

reinforcing strip'lOO suitably secured to the slide 95 is formed with stop shoulders lOl `at opposite edges of its front end,.arranged to'abut against the front end of the table so` as to lilxnit the rearward movement f said slide 95 under the influence of al spring 102 which connects a pin 103 projecting down- -wardlyfroin the slide, With a fix-ed hook .lll-l.

-for a purpose presently explained. The upper surface of the forward end ofv the slide )Vlien a device a. lands in substantially the v `position shown'in Fig. 7, it would be liable to be slightly turned from a. proper posi tion. lts prongs, if not entering; the re- 1 cessesr 99, should be made to' do so, and 'this effect is produced by the slight play which 1 the pusher has relatively to the slide 95, during the first-advance of the pusher. p While the pusher advancesthe distance determined by the pin 97 of the pusher riding along' the slot 96 of the slide, thebeveled and pointed toe 77 of the pusher passes between two of the prongs c2 of the device a and then pushes the device alongr so that' other' prongs of the latter. engagingthe beveled margins of re cesses lllg'wil-l be turned to exactproper pon other words, 'the first forwardA movement ofthe pusher causes the prongs y of the device ajto so engagethe recesses of the steel facing 98 as to properly center'the device and cause" it to be properly forced y between the jaws 55. f'

The escapement arm 89 is acted upon by a springr 105 (Figs. 2 and 8), so as to nor-1 "mally hold the escapement with its pins in' the position shown rin Fig. 8, the moveuaient of the pawllt, actuated by the pusher, as

ing-Figs. 6 and 9 to 16, inclusive. The upper end of the chute is shown as providedl with a coupling member 109, (Fig. 16,) Which is merely for use in temporarily connecting with said chute a loading device. A

' cover-strip 110l against which the top surface 'of the device a` may ride, is suitably supported, as by a series of -brackets,. 111,

112, 113, 114. v Secured to the upper end of the cover plate 110 Yis a sample device or indicator 115, this being either one of the devices a itself, or a correct dummy thereof',

said indicatorbeing so like the devicefs'a, and

so positioned that aperson supplying devices a. to the chute Will see at once the proper' position for inserting the devices under strip 110 so that vthey Will properlyl` ride down the chute.

A bracket 116 (Figs. 8 and 13) is secured to the stri-p 110 and `carries a pivot-screw 117 for the escapement device, said escapement device'includin'g" not onlythearm 39 Ihereinbeiiore mentioned, but also .a plate 118 integral with ,or'rigidly connected to said arm. 89, which plate 118Acarries the devices which I shall now describe. The plate 118 has a pin 119 (Fig. 14) adapted to move ythrough a liole 120 inthe strip 110. An arm 121 is pivotally connected at 122 toitheA plate 118, and has a pin 123 passing through another hole in the strip 110,- as clearly shown in Figs. 14 and 15'. A screw 124 passes through ,a hole in arm 121 and is secured to the plate 118. A spring'125 coiled about the screw, is confined betweenl the head of the screw and a `Washer 126 which bears upon the upper face of the arm 121. Said arm 121' has a spring contact 127 secured .to it by suitable'means, such as screws.

128 (Fig. 16), suitable material 129 being provided to insulate the contact 127 from the part or parts Which carryit.

The contact. 127 coperates With-two' con i tats 130 carried by an insulating block 131 suitably connected to the chute, so that when '-thecontact 127 is in the 'position shown-in of which circuit consist of the two contacts 130.- From one of the insulated contacts Fig. 15, it will act as a switch to complete a circuit presently described, the terminals 130, a Wire '132 (Figs' and 116) leads topa signal 133 (Fig. 4), such as an electric-buzzer. A wire 134 connects the other insuA lated contact 130 with a battery 135' (Fig..1). A Wire 136 connects the battery and buzzer.

Whenever the contact 127 occupies the po-. sition shown in Fig. 15, it completes' the circuit and the buzzer indicates to the operator that a device a is about to be lfed to the `cle'enching mechanism in. an incorrect posi# tion,l or that the chute is empty, as Will be presently explained.

y While the margins of the devices a.y are elliptical or. elongated, their jaws a2 which grip the complemental stud members' (not shown), andthe holes which enable such stud membersto enter betvveen'said jaws,

-, are not at the mid-length of the major axes of the devices.; in other Words, --they' are `eccentric. 4Such devices cannot be 'readily' m handled or supplied by a maga-zine, orchute and feed devices, `of usual form. ,With my v improvements abovedescribed, when the chute is properly loaded, with all of. the devices turned" the.- same Way, or ,in other 'Words, With'their major axesextendino in y y -the same direction, their holes will bein aga .7

to oscillate' the escapement'from the'v position shown in Fig. 6 to that shownlinllg.

14, releasing the lowerrnost device a and letting it slide downjthechute to the position shown in Fig. 7l `At the same time, the'pin 9'5 123, carried by the yielding arm 121,'bears frictionally on the upper surface of the next device a (Figs. 9 and 14) `with sufficient pressure'to arrest the devices until the es capement returns to the Figf 6 position. 100 jf, however, a device comes down the chute turned wrongly, end kfor end as in Fig. 10,v

then the holevof that device is in position to f let the pin 123 enter it as shown in Fig. 15, thus permitting contact 127'. to `bear on the 105 two contacts .130 and cause the buzzer to sound, after which the operator can release 7 that device a by firstv operating cam Y,57 tof open the jaws 55 and then operating lever l 68 once. Of course, if the chute should be 1,10.

empty, the circuit will be completed inthe same manner asl shown in Fig. 15. If va device a 1s placed 1n the chute 1n some 1nter' mediate lncorrectjposition, such as indicated inFigs. ll-and 12, then at/least, one of its .1115

prongs a will be close to theouter side of the chute. To arrest such* an incorrectly placed, device, I provide stop vyings137 'I (Figs. 8, 9, and l2) near the escapement said stops being so locatedas to be in the .12o-

path of one or mo'reprongs if in the position of Fig. 1 2, but to permit the prongs to pass,

itin the lcorrect'position of Fig..9. Suchf i' incorrect positioning as shown in Figs. 11rv and 12, seldomoccurs, but when it does, and

that device is arrested'by a stop vi/ing, thefv nextaction "ofl the escapernent causes the buzzer to sound thel same, as though' the chute was empty. Then the l operator can,.-
